Bolt fracture influences whether the bonding strength of blower fan tower barrel, and then has influence on the safety of blower fan.Due to single bolt
Fracture influences limited to fan safe, and the current way of current industry is regular visit of disposing available manpower, the method inspection such as by visual observation
Look into the presence or absence of bolt fracture situation.Because tower bolt is distributed on different height, patrol officer needs to climb blower fan, increases
Human cost and security risk；Simultaneously as it is regularly, the bolt of batch to be likely to occur between patrolling and examining twice to patrol and examine
Fracture, seriously threatens the safety of blower fan.
There are the fracture or loosening of certain methods monitoring bolt by way of automation in the market（CN104851246A
Deng）.Its shortcoming is complicated device, relatively costly.
The content of the invention
The utility model is to provide for a kind of device for monitoring bolt fracture, and the device is vertically-mounted for monitoring
Connecting bolt whether breaking releasing, it is to avoid frequently other expenses of human inspection and correlation；Bolt is represented using electric signal
Breaking state, can access blower fan control system, be supported for air-blower control logic optimization provides data；And by remote monitoring
System obtains the information whether connecting bolt comes off, and can arrange maintenance of fan work according to actual conditions；And by flexible
Installation cabling mode, Primary Location can be carried out to failure bolt；The apparatus structure is simple, it is easy to installs and safeguards, reliability
It is higher.
To achieve the above object, the technical solution of the utility model is：A kind of device for monitoring bolt fracture, including
Vertically-mounted multiple connecting bolts, are respectively mounted monitoring device on ring flange on multiple connecting bolts, and by connecting wire
Monitoring circuit is accessed after concatenation.
The monitoring device includes insulating base, socket piece, connecting wire, plug piece, and the socket piece is by conducting metal
Piece is processed, including base plate and mounting hole, spring clip and the part of wiring point three, and the mounting hole on base plate is matched somebody with somebody by mounting pin
Close connection insulating base；The plug piece is processed by conducting metal, including at contact portion and wiring, contact portion with insert
The spring clip of seat piece is fitted close, and is the fixing point of connecting wire at wiring.
After the connecting bolt installation, the bolt is fixedly connected insulating base, spring clip below ring flange
Piece opening direction points to side adjacent bolt, and the plug piece connected by connecting wire on spring clip is inserted on the adjacent bolt
In fixed socket piece.
The connecting wire is the thin electric wire of single, and its length is+2 centimetres of adjacent two bolt-centers point distance.
The beneficial effects of the utility model are：
Artificial regular visit is changed to automatic monitoring by the utility model, reduces human cost, improves reliability；Make
Monitored with loop opening and closing signal, it is simple efficiently to coordinate the different modes of connection, can be with Primary Location trouble point.This bright structure letter
Single, production, installation cost are relatively low.System reliability is higher.
Brief description of the drawings
Fig. 1 is the apparatus structure schematic diagram for monitoring bolt fracture of the present utility model；
Fig. 2 is monitoring device schematic diagram of the present utility model.
Specific embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of device for monitoring bolt fracture, including multiple connections vertically-mounted on ring flange 1
Bolt 2, is respectively mounted monitoring device 3, and access monitoring circuit after connecting wire 4 is concatenated on multiple connecting bolts 2.Up and down
Flange is attached by bolt 2 and nut assembly, and monitoring device 3 is fixed on 2 lower sections of each bolt, and by connecting wire
4 connections are incorporated to control loop；Under normal condition, loop has electric current to pass through；When bolt 2 is broken, the latter half is dropped so that a certain
Section lead plug is extracted from monitoring device, so as to destroy the closure state in loop so that loop disconnects；By monitoring circuit electricity
The disconnected monitoring for being capable of achieving the fracture of bolt 2 of circulation.
As shown in Fig. 2 monitoring device 3 include insulating base 7, socket piece 5, connecting wire 4, plug piece 6, socket piece 5 by
Conductive metal sheet is processed, including base plate and mounting hole, spring clip 8 and the part of wiring point three, and the mounting hole on base plate leads to
Cross the mating connection insulating base 7 of mounting pin 9；Plug piece 6 is processed by conducting metal, including at contact portion and wiring, is connect
Contact portion point is fitted close with the spring clip 8 of socket piece 5, is the fixing point of connecting wire at wiring.Spring clip 8 can with insert
The contact portion of head 6 is engaged, and relative position is fixed during both stable bonds, and the certain external force effect of needs could be by it
Separate.
Insulating base 7 is to use insulating materials（Such as plastics）Process, by be slightly less than respective bolt head insulation board and
Mounting pin two parts are constituted.Mounting pin is the columnar protrusions on base plate, and socket piece can be fixed on insulation board.
Connecting wire 4 is the thin electric wire of general single, depending on its length is with bolt installation site and cabling mode.Work as installation
Mode is for when being arranged in series substantially, length is about+2 cms of the adjacent central point of two bolt 2 distance.
After connecting bolt 2 and nut assembly installation, the part of bolt 2 and nut assembly below flange will insulate
Base plate 7 is fixed, and the opening direction of spring clip 8 points to side adjacent bolt 2.Connection will be passed through on spring clip 8 on bolt 2
The plug piece 6 of the connection of wire 4 is inserted in the socket piece 5 of monitoring device 3 fixed on the adjacent bolt.
When the monitoring device 3 on ring flange 1 is after being linked to be a close ring with upper type, ring is broken in place
Open, both sides are respectively connected in monitoring circuit.Now monitoring circuit is closed circuit.
When bolt 2 is broken, 2, bolt（May band part fracture screw rod）Fallen from vertical flange hole,
Being fixed on the upper monitoring device 3 of 2, bolt can also be fallen together, and the monitoring that the pulling force of generation of dropping will be installed on both sides bolt 2 is filled
Cooperation between the plug piece 6 and socket piece 5 of the monitoring device installed on the plug piece 6 and socket piece 5 and break bolt 2 put is broken
Bad, now monitoring circuit is opened a way.
The present apparatus is installed by taking three sections of towers as an example, on the connecting bolt between foundation ring and first paragraph tower and is connected；
The present apparatus is installed on the connecting bolt between first paragraph tower and second segment tower and is connected；In second segment tower and the 3rd section
The present apparatus is installed on the connecting bolt between tower and is connected；Pacify on the 3rd section of connecting bolt between tower and yaw
The dress present apparatus is simultaneously connected.The road signals of Jiang Zhe tetra- access blower fan control system by relay respectively.Now, break once there is bolt
Split and come off, corresponding loop will be changed into open circuit.Control system receives this signal and the response that is correspondingly processed（Alarm, stop
Machine etc.）.
